Real reviews from real patients recovering from Achilles rupture
Total game changer for sleeping while recovering!
Finally got the restful sleep I needed. The cast and heavy dirty boot made sleep tough. If you're recovering from an achilles rupture buy this immediately.
Perfect splint for achilles injury recovery
It literally takes a few secs to put on and remove. Its comfortable as well. Highly recommend.
Life Saver!
This worked great and kept me from having to wear my big clunky walking boot to bed! So glad I found this. I couldn't sleep with that walking boot at night!! Great product.
Eine absolute Erleichterung!
Nach der OP an der Achillessehne war diese Schiene eine Erleichterung in der Nacht! Würde ich auf alle Fälle empfehlen wenn man wieder durchschlafen möchte!
Superb
Really useful after my dreadful Achilles tendon tear when I didn't want to wear the boot in bed!
Night time saviour
This is a saviour for night time wearing. So much easier than the big boot. Five weeks down and another five or six to go. Would have struggled with the full boot.
Peace of mind for Achilles injuries
A great alternative to wearing the walking boot to bed, without worrying about inadvertently straightening or knocking your foot.
Wonderful device and splendid service
Brilliant device. Arrived the day after it was ordered. Delighted in all respects.

athleteSlimmer, lightweight, and allows free movement while protecting the tendon
The Thetis Splint is a lot slimmer and far more lightweight than the orthopaedic boot I was sleeping in.
